Fifth Embodiment

A bicycle operating system 512 in accordance with a fifth embodiment will be described below referring to FIGS. 12 and 13. The bicycle operating system 512 has the same configuration as the bicycle operating system 12 except for the transmission controller 26. Thus, elements having substantially the same function as those in the above embodiments will be numbered the same here, and will not be described and/or illustrated again in detail here for the sake of brevity.

As seen in FIG. 12, the bicycle operating system 512 comprises the bicycle operating apparatus 14 and a transmission controller 526. The transmission controller 526 is configured to control at least one transmission in accordance with a transmission route in response to at least one of the first control signal SG1 and the second control signal SG2. In the illustrated embodiment, the transmission controller 526 is configured to control the first transmission TM1 and the second transmission TM2 in accordance with the transmission route in response to at least one of the first control signal SG1 and the second control signal SG2.

The transmission controller 526 includes a first transmission controller TC51 and a second transmission controller TC52. The first transmission controller TC51 includes a first control unit CU51. The second transmission controller TC52 includes a second control unit CU52. The first control unit CU51 has substantially the same configuration as that of the first control unit CU1 in accordance with the first embodiment. The second control unit CU52 has substantially the same configuration as that of the second control unit CU2 in accordance with the first embodiment.

The first control unit CU51 includes the processor PR21 and a memory M521. The first control unit CU51 is configured to store the transmission route in the memory M521. The second control unit CU52 includes the processor PR22 and a memory M522. The second control unit CU52 is configured to store the transmission route in the memory M522.

FIG. 13 shows a shift table including gear ratios, a total number of teeth of each sprocket element in the chain wheel BC11 (“FS”), and a total number of teeth of each sprocket element in the rear sprocket BC2 (“RS”). The first control unit CU51 of the first transmission controller TC51 is configured to store the shift table for the bicycle operating system 512. In the illustrated embodiment, the first transmission TM1 has low and top gears as the gear position. The second transmission TM2 has first to eleventh gears as the gear position.

As seen in FIG. 13, the first control unit CU51 is configured to store a route R1 in the memory M521 (FIG. 12). The second control unit CU52 is configured to store the route R1 in the memory M522 (FIG. 12). The route R1 includes synchro-shift points which are each circled with a single circle. In the illustrated embodiment, the transmission controller 526 is configured to control both the first transmission TM1 and the second transmission TM2 to change gears at the gear position corresponding to the synchro-shift point in response to a single shift signal.

In the illustrated embodiment, the route R1 is used for both upshifting and downshifting. The transmission controller 526 can be configured to store an upshift route for upshifting and a downshift route, which is different from the upshift route, for downshifting if needed and/or desired.

As seen in FIG. 13, in the route R1, first to seventh gears of the first transmission TM1 are used for low gear of the second transmission TM2. Sixth to eleventh gears of the first transmission TM1 are used for top gear of the second transmission TM2. Namely, thirteen gear positions on the route R1.

The transmission controller 526 has a synchro mode and a normal mode. In the synchro mode, the transmission controller 526 is configured to control at least one of the first transmission TM1 and the second transmission TM2 in accordance with the transmission route in response to a single shift signal from the bicycle operating apparatus 14. In the normal mode, the transmission controller 526 is configured to control the first transmission TM1 and the second transmission TM2 as well as the first embodiment, for example.

As seen in FIG. 10, the bicycle operating system 512 further comprises a mode selector 586 configured to allow the user to select a shifting mode among the synchro mode and the normal mode. The mode selector 586 is provided in the first operating device 22, for example. The wireless transmitter WT1 wirelessly transmits a shifting mode selected via the mode selector 586 to the transmission controller 526. The transmission controller 526 is configured to set the shifting mode based on the shifting mode selected via the mode selector 586.

In the synchro mode, the additional operating member 32 is operated by the user for upshifting. The additional operating member 34 is operated by the user for downshifting.

In a case where the first transmission TM1 is in sixth gear and the second transmission TM2 is in low gear in the synchro mode, the first transmission controller TC51 controls the first transmission TM1 to upshift in response to the first control signal SG1. Meanwhile, the second transmission controller TC52 controls the second transmission TM2 to keep in low gear regardless of the first control signal SG1.

In a case where the first transmission TM1 is in sixth gear and the second transmission TM2 is in low gear in the synchro mode, the first transmission controller TC51 controls the first transmission TM1 to downshift in response to the second control signal SG2. Meanwhile, the second transmission controller TC52 controls the second transmission TM2 to keep in low gear regardless of the second control signal SG2.

In a case where the first transmission TM1 is in seventh gear and the second transmission TM2 is in low gear in the synchro mode, the first transmission controller TC51 controls the first transmission TM1 to downshift and the second transmission TM2 to upshift in response to the first control signal SG1.

In a case where the first transmission TM1 is in sixth gear and the second transmission TM2 is in top gear in the synchro mode, the first transmission controller TC51 controls the first transmission TM1 to upshift and the second transmission TM2 to downshift in response to the second control signal SG2.

With the bicycle operating system 512, the transmission controller 526 is configured to control at least one transmission in accordance with the transmission route in response to at least one of the first control signal SG1 and the second control signal SG2. Accordingly, it is possible to simplify the input operation. Furthermore, since the bicycle operating apparatus 514 includes the hydraulic operating unit 16, it is possible to improve ease of use relative to the bicycle operating system 512.
